Question

编辑：我设法通过将WebMethod设置为void而不是字符串然后手动写入响应来实现它的工作：

        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.ContentType = "application/json; charset=utf-8";
        HttpContext.Current.Response.Write(json);
        HttpContext.Current.Response.Flush();
        HttpContext.Current.Response.End();

我有一个webmethod，它返回一个序列化的json对象，下面是一个例子：

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string PostDropDowns()
    {

        TestClass t = new TestClass()
        {
            abc = "this has been sent over",
            Strings = new List<string> { "fdfdfd", "fdfdfdf" }
        };
        var json = JsonConvert.SerializeObject(t);
        return json;
    }

JSON text =

{"abc":"this has been sent over","Strings":["fdfdfd","fdfdfdf"]}

在我的c＃UWP应用程序中，我称之为webrequest

 public static void GetDropDowns(string address)
    {
        //create the HTTPWebRequest
        HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
        request.Method = "POST";
        request.ContinueTimeout = 20000;
        // request.Accept = "text/json";
        request.ContentType = "application/json; charset=utf-8";


        try
        {

            //get the response
            using (var response = request.GetResponseAsync().Result)
            {
                StreamReader reader = new StreamReader(response.GetResponseStream());
                var responseFromServer = reader.ReadToEnd();

                var dds = JsonConvert.DeserializeObject<TestClass>(responseFromServer);

            }

        }
        catch (Exception e)
        {
            //error handling in here

        }
    }

然而，我回来的json看起来像这样：

{"d":"{\"abc\":\"this has been sent over\",\"Strings\":[\"fdfdfd\",\"fdfdfdf\"]}"}

因此，当反序列化回我的TestClass时，标题和字符串都为空。

我如何预防d通过或绕过它？

防止返回的json被包裹在{d：
